ios - How to update our static library architecture for suporting arm64 Build?

Question

Few days ago i create static-library (Universal) that work's fine with Xcode5.0 SDK7. After Update Xcode5.1 with SDK7.1 that not work if i select simulator iPhone Retina(4-inch 64-bit). Then i am going to update my lib with Bellow setting change.

I do the same for three Target:-

For sporting simulator as well as device i put Universal lib and in to this i run script this:-

After this i Build Again lib and used as i done Before in to my project. But still getting same issue with iPhone Retina(4-inch 64-bit) Undefined symbols for architecture x86_64:

---

So, My question is that is there any additional change required for updating lib for arm64 or i did any mistake in above step. Please current me if i am wrong.

what change needed for update my static-library for supporting 64Bit architecture

NOTE:

I am asking for my own created Library Update. i am not using third-party Library. Update

I used this lipo -info testingLibImport/libLibNSlog.a command in to my Terminal that output is:

Architectures in the fat file: testingLibImport/libLibNSlog.a are: armv7 armv7s i386 arm64

Another solution I found with XCode 6.4 is to add ONLY_ACTIVE_ARCH=NO and not specify the architecture. So

xcodebuild -target TargetName ONLY_ACTIVE_ARCH=NO -configuration ${CONFIGURATION} -sdk iphonesimulator BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}"

Will build i386 and x86_64 architectures in your library.

Here's my full universal lib run script to build all the architectures.

# define output folder environment variable
UNIVERSAL_OUTPUTFOLDER=${BUILD_DIR}/${CONFIGURATION}-universal

# Step 1. Build Device and Simulator versions
xcodebuild -target TargetName ONLY_ACTIVE_ARCH=NO -configuration ${CONFIGURATION} -sdk iphoneos  BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}"
xcodebuild -target TargetName ONLY_ACTIVE_ARCH=NO -configuration ${CONFIGURATION} -sdk iphonesimulator BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}"

# make sure the output directory exists
mkdir -p "${UNIVERSAL_OUTPUTFOLDER}"

# Step 2. Create universal binary file using lipo
lipo -create -output "${UNIVERSAL_OUTPUTFOLDER}/lib${PROJECT_NAME}.a" "${BUILD_DIR}/${CONFIGURATION}-iphoneos/lib${PROJECT_NAME}.a"                "${BUILD_DIR}/${CONFIGURATION}-iphonesimulator/lib${PROJECT_NAME}.a"

# Last touch. copy the header files. Just for convenience
cp -R "${BUILD_DIR}/${CONFIGURATION}-iphoneos/include" "${UNIVERSAL_OUTPUTFOLDER}/"
